Gearhead Garage: The Virtual Mechanic is a PC game where players repair and customize late model cars and trucks. It was created by Mekada, endorsed by Snap-on Tools, and published in 1999 by Head Games (subsequently acquired by Activision).

Since there is no feature for driving the cars, this rather novel game corresponds most closely to the "simulation" genre, although it could be argued that Gearhead Garage introduced an entirely new "bolt-em up" paradigm. The appeal is reminiscent of taking things apart in real life -- players can completely disassemble the engine, repair the individual parts, reassemble them, and then exhibit the completed result in their 3D "car lot". The game also features a series of "jobs", wherein the player fixes vehicles cars owned by fictional characters. (Wikipedia)

Free parts
Take parts off people's cars then enable the "Free job" code. You will still have the parts under that car name and still get paid the full amount.

HINTS

God-like mode
Do all the jobs you can. After it says that there are no more jobs, get a cheap car from the auction, fix it up, and try to get more than $20,000, which will get you to God-like mode.

Easy money
Please note: This does not work on high priced or third party cars. Buy an old or new junker from the auction. Do not repair this car. Just take and buy a new car door from the catalog. Put the door or whatever part on the car and auction it. This will generally make anywhere from $78 to $1,000 profit.
